Collaboration with colleagues benefits every workplace, but in education it is even more essential and a critical factor in improving classroom learning and success. NCTM's 2012 Yearbook provides an opportunity and an important resource for exploring a wide variety of perspectives on the nature and design of professioanl collaborations as they relate to mathematics teaching and learning. The book examines effective elements for successful collaborative partnerships, discusses the role of various stakeholders, and explores traditional and nontraditional methods of promoting and influencing teacher partnerships such as coaching and mentoring.
